AmazonExternal USB batteries are an essential item for any trip, but that's especially true for outdoor trips.
Heading outdoors and unplugging for a week can do wonders for your psyche.
But emergencies can, and do, happen.
In those cases, it's important to have a fully charged phone, and one that will stay alive for a long time.
Innoo Tech's battery is "lifeproof" and, more importantly, can recharge through solar power. The battery itself has a capacity of 10,000mAh, more than enough to fully recharge a smartphone.
It has two regular USB ports, so you can charge multiple devices if need be, and uses PowerSmart technology to determine how quickly to charge whatever you've plugged into it.
From a durability standpoint, this battery can withstand a fair bit more than most. It has an IPX5 waterproof rating, which isn't enough to survive sustained time underwater, but is enough to survive exposure to rain or water splashing. It's also dust- and shock-proof, so it'll be fine if you take it to the beach, or accidentally drop it.
You can charge this battery through its SUNPOWER solar panel, which Innoo Tech claims is more efficient than other, similar panels, or by plugging it into a standard power brick with a Micro USB cable. My favorite feature, aside from solar charging, is that this battery has a built-in light, which can come in handy when camping or during a loss of power.
If you travel outdoors a lot, especially if you're around water, it's worth picking this battery up. Given its high capacity, it's also a great value in general. So if you haven't yet bought an external USB battery, this is a good deal.
